Title: Improvements in Telegraphic Apparatus for Double Transmission by Pulsatory and Continuous Currents.
Filed: 1902-08-23
Granted: 1902-10-23
Abstract: 18,580. Wise, W. L., [Crehore, A. C.]. Aug. 23. Telegraphs.- Relates to systems of telegraphic signalling by means of pulsating and continuous c u r - rents over a common line, means being also described for translating to or from a combined line or to branch lines. The method of working consists in balancing the disturbing effects of e a c h system on the other by means of shunts. Fig. 1 shows a line with five stations in series, of which A, C, and Ware arranged for signalling by both methods, while B, V are for continuous-current working only. At station A, the continuous-current receiver 3 acts as an inductance shunt to the pulsating-current receiver 4, which has low ohmic resistance and an almost closed magnetic field, and is in series with a condenser 8. Both receivers are shunted by a non-inductive resistance 9, by which the disturbing influence of each side is shunted. The direct-current transmitter 1 is shunted by a condenser 8 or impedance coil 12<1>. The pulsating- current transmitter 2 is arranged as a shunt across the coil 12<1> and the receivers, a safety coil 13 being included in the shunt to prevent the shortcircuiting of the generator 6. In a modified form, the two transmitters are arranged in series, and are in series with the receivers, which are in parallel. The receivers are preferably differentially wound or shunted as previously described, or the direct-current receiver may be employed unshunted. The pulsating-current receiver has two coils in one arm, one coil of which is shunted when transmitting, so as to leave the receiver perfectly balanced. The current transmitter employed is preferably of the continuity-preserving type, and has an additional contact-spring on the lever which maintains the shunt connection until the battery connection is made. A further arrangement is described in which a combined line is arranged to separate and translate the two superimposed messages on to two separate branch lines. The translating-station is arranged with the receivers in the arms of a loop and arranged to operate by magnets the transmitters connected to the separate lines. The incoming currents from the separate lines are arranged to operate the translating-transmitters of the combined lines, and, at the same time, switches are operated to prevent the translating-receivers from re-acting on the branch transmitters.

Title: Improvements relating to Locks and Latches.
Inventor: ALMAN JOHN C
Filed: 1903-02-17
Granted: 1904-01-14
Abstract: 3754. Alman, J. C. Feb. 19, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Locks, key; latches.-A door latch, which is shot by a gravity lever, is provided with means for locking it in the shot position. The latch 20 is provided with a bevelled head, and is adapted to slide between guides arranged in the casing 10. The latch is provided with two recesses 22, 22<a> so as to be reversible, one of these recesses being engaged by a nose 59 of a pivoted lever 50, arranged to fall by gravity into such a position that the latch is shut. An additional weight may be pivoted to the lever 50 to assist in shooting the bolt. The lever 50 is cut away to receive a draw-bar 40, which is slotted at one end to take over a projection or sleeve 57 on the lever, while at the other end it has an opening 43 to receive the follower 30 on the knob spindle 34. A lug or wrist 45 on the draw-bar is adapted to engage a shoulder 51 on the lever to operate the same, the draw-bar being moved by the engagement of the follower arms with the walls of the opening 43. The lever 50 bears on bosses 16 on the casing, and is provided with a projection 58 of soft material to reduce the impact, when it comes in contact with the top of the casing. A locking-lever 60, which normally rests on a stop 13, may be turned to abut against a projection on the lever 50 and so lock the latch in the retracted position. This lever 60 is provided with a disc 63 having an opening for the engagement of the operating-key. In cups formed in the side walls of the casing about the keyhole, are located wards separated by washers, these wards having projections in the engagement with recesses in the cups. The disc 63 is provided with flanges 63<a> taking over the cups. In a modification, the disc is located within the cups. Rings 4, or a ring. are arranged to encircle the cups, and are provided with projections 7, 7<a>, Fig. 9, adapted to engage recesses in the flanges 63<a>, and with inwardly-projecting lugs 5, 6 for the engagement of the key. The lugs 5, 6 project through recesses in the cups. The projections 7 are normally in engagement with the flanges to secure the disc 63 against rotation. Upon inserting the key, the shoulders 8, Fig. 5, on the bitt engage the lugs 6 and raise the projections 7 clear of the flanges. Should the rings 4 be raised too high, the projections 7a come into engagement with the flanges and prevent rotation of the disc. The key bitt is also adapted to engage the projections 5 and force the rings 4 downwards, in case they do not fall by gravity. The lug 7a may be dispensed with. The locking- device may be employed in connection with a separate locking-bolt. The face-plate 18 of the lock is provided at one end with a hook 18<a> adapted to take over a projection 17 on the casing, and at the other end it is fixed to a projection 17<b> on the casing.

Patent GB-190306395-A (GB)
Title: Improvements in Receptacles for Coins.
Inventor: BISHOP ROBERT HODGES
Filed: 1903-03-19
Granted: 1904-02-18
Abstract: 6395. Bishop, R. H., and Down, W. March 19. Money boxes.-In a money box of the type intended to be set to receive a number of coins of a definite value and to remain closed until that number has been inserted, the registering and controlling mechanism is mounted on both sides of a metal plate e, Figs. 1, 2, and 4, within the lid b, which is held closed by the engagement of a spring bolt c under a bevelled catch d. The mechanism is set by turning the pence and shillings wheels i, j on the underside of the plate e until the required sum is indicated by the numbers, on the upper side of the wheels, which show through openings k in the plate e and corresponding glazed openings in the lid b. The lid being then closed, the spring w forces the bolt c under the catch d. When a coin, either a penny or halfpenny, is to be inserted, a sliding bolt p above the plate e is pulled back by means of a peg 2 projecting through a slot in the lid, so that a pivoted cover h can then be raised clear of the slit f into the position shown in Fig. 2, the tail of the cover h working in a recess s in the bolt p. The coin 1 is then pushed in over the bevelled springs 4, which prevent return, and is held by them until the cover h is turned down and the bolt p drawn forwards. While moving towards the opening g through which it falls into the box a, the coin 1 bears against a projection n and rotates a lever l so that a pawl m rotates the pence wheel i, either through one or two teeth according as the coin 1 is a halfpenny or penny. When the bolt p is returned, it strikes the projection o and returns the lever l, the wheels i, j being held by springs y, z. Once per revolution of the wheel i, a projection t on it moves the wheel j through one tooth. When the last coin necessary is being inserted, a pin u on the wheel i acts in a notch in the bolt c to push the bolt c back. Before the bolt c is released from the pin u, its rear end depresses a spring x to lock the bolt p in its forward position, so that the box cannot be locked until the wheels i, j have been re-set. To provide for the insertion of a penny to open the box when only a halfpenny is required to complete the sum for which the mechanism was set, the notch in which the pin u acts is formed so that the wheel j may be rotated slightly after the bolt c is drawn back and held free of the catch d.
Patent GB-190312119-A (GB)
Title: A Method of Receiving Electrical Vibrations with the Use of Electrolytic Cells.
Inventor: EVANS WILLIAM EDWARD
Filed: 1903-05-27
Granted: 1903-07-02
Abstract: 12,119. Evans, W. E., [Allgemeine Elektricitõts-Ges.]. May 27. Telegraphs.-Consists in a method of receiving electrical vibrations in which an electrolytic cell is included as a wave detector in the receiving-circuit. The cell may be a primary galvanic-battery cell consisting of two electrodes dipping in an electrolyte, such as dilute sulphuric acid or a lye. One at least of the electrodes has a very small superficial area, being formed, for example, of platinum wire (r a carbon filament about ¢ a millimetre long and <1>/100 to <1>/000 of a millimetre in diameter. The other electrode may be of the same material, or of another material which is differently placed in the scale of electric potentials and is not attacked by the electrolyte. The cell may be enclosed by glass and sealed up airtight. The current temporarily produced on joining the wires is stopped by polarization by a coating of gas, and is re-started by electromagnetic impulses of high frequency. An auxiliary battery of greater electromotive force than that of the foregoing cell may be connected in series with it, in order to produce a pulsating current the amplitude of which is increased when the counter electromotive force of the cell is diminished by the action of the electrical waves. The potential of the auxiliary battery is adjusted accurately by coupling it up with a resistance provided with adjustable contacts. The cell may be connected in the receiving-circuit, which is accurately tuned to the frequency of the transmitter, by connecting one pole with the aÙrial conductor and the other to ear th, or to an equivalent counter capacity ; or the connection may be made by a shunt circuit or inductively. For indicating the current vibrations of the cell, an ordinary listening-telephone is employed ; or a direct-current relay which does not act until the electrical vibrations have increased the current by a determined amount; or a vibrating relay the vibrations of which are tuned to the frequency of the transmitter sparks.
